Current Client: Schedule a time for me to call you back. Clients who pay hourly will be billed according to the terms of their representation agreement for the actual time spent during the phone call.
Potential Client: Schedule a brief phone call with me, and I will tell you whether or not I can potentially represent you.
Other (Opposing Counsel/Case Witness): Don't want to play phone tag? Anyone other than salespeople or marketers may schedule a phone call back from me.
